 ## [3.27.1] - 2026-02-15
 ### Added
 - **Grepai MCP documentation** (`guide/mcp-servers-ecosystem.md`)
  - New "Code Search & Analysis" section (~130 lines): semantic search, call graph tracing, setup guide
  - Privacy: fully local (Ollama + nomic-embed-text), zero data exfiltration
  - Token efficiency comparison: grepai 2-3K tokens vs Grep+Read 15K for same results
  - Cross-referenced from `reference.yaml`
 - **2 new resource evaluations** (both scored 2/5 — not integrated)
  - `system-prompts-opus-4-6-update.md`: Re-evaluation of x1xhlol system prompts repo (Opus 4.6 update), still redundant
  - `2026-02-14-simone-ruggiero-qmd-token-savings-medium.md`: qmd token savings tool (Medium article), claims unverifiable, redundant with grepai
 - **2 new hook templates** (`examples/hooks/bash/`)
  - `rtk-baseline.sh`: SessionStart hook — saves RTK gain baseline for delta tracking
  - `session-summary.sh`: SessionEnd hook — auto-displays session summary (inspired by Gemini CLI)
 - **Watch list entry**: o16g (Outcome Engineering) — emerging framework by Cory Ondrejka (ex-VP Google/Meta)
 ### Changed
 - **RTK documentation overhaul** (v0.7.0 → v0.16.0, 446 stars, rtk-ai org)
  - Updated 15+ files across guide + landing: org migration (rtk-ai/rtk), removed fork distinction
  - Added: Python, Go, Homebrew, hook-first install, `rtk init`, `rtk tree`, `rtk learn`
  - Removed outdated ls/grep warnings (bugs resolved in v0.16.0)
  - Evaluation score: 4.5/5 → 5/5 (446 stars, [700+ Reddit upvotes](https://www.reddit.com/r/ClaudeAI/comments/1r2tt7q/))
  - Landing site updated: Homebrew install, new command grid (cargo/python/go), removed name collision warning
  - `~/.claude/CLAUDE.md`: replaced fork install with cargo/Homebrew
 - **Exports deprecated** — Moved `kimi.pdf` and `notebooklm.pdf` to `exports/deprecated/` (generated from ~9K line v1.x era, guide now ~19K lines)
 ### Fixed
 - **Fact-check corrections across 22 files** (866 insertions, 308 deletions)

-> **Claude Code from beginner to power user.** Exhaustive documentation, production-ready templates, agentic workflow guides, quiz, and a cheatsheet for daily use.
+> **6 months of daily practice** distilled into a guide that teaches you the WHY, not just the what. From core concepts to production security, you learn to design your own agentic workflows instead of copy-pasting configs.
 > **If this guide helps you, [give it a star ⭐](https://github.com/FlorianBruniaux/claude-code-ultimate-guide/stargazers)** — it helps others discover it too.
 ---
 ## 🎯 What You'll Learn
 **This guide teaches you to think differently about AI-assisted development:**
 - ✅ **Understand trade-offs** — When to use agents vs skills vs commands (not just how to configure them)
 - ✅ **Build mental models** — How Claude Code works internally (architecture, context flow, tool orchestration)
 - ✅ **Master methodologies** — TDD, SDD, BDD with AI collaboration (not just templates)
 - ✅ **Security mindset** — Threat modeling for AI systems (only guide with 18 CVEs + 341 malicious skills database)
 - ✅ **Test your knowledge** — 264-question quiz to validate understanding (no other resource offers this)
 **Outcome**: Go from copy-pasting configs to designing your own agentic workflows with confidence.

 ## 📊 When to Use This Guide vs Everything-CC
 Both guides serve different needs. Choose based on your priority.
 | Your Goal | This Guide | everything-claude-code |
 |-----------|------------|------------------------|
 | **Understand why** patterns work | Deep explanations + architecture | Config-focused |
 | **Quick setup** for projects | Available but not the priority | Battle-tested production configs |
 | **Learn trade-offs** (agents vs skills) | Decision frameworks + comparisons | Lists patterns, no trade-off analysis |
 | **Security hardening** | Only threat database (18 CVEs) | Basic patterns only |
 | **Test understanding** | 264-question quiz | Not available |
 | **Methodologies** (TDD/SDD/BDD) | Full workflow guides | Not covered |
 | **Copy-paste ready** templates | 108 templates | 200+ templates |

 **4 unique gaps no competitor covers:**
 1. **Security-First** — 18 CVEs + 341 malicious skills tracked (no competitor has this depth)
 2. **Methodology Workflows** — TDD/SDD/BDD comparison + step-by-step guides
 3. **Comprehensive Reference** — 19K lines across 16 specialized guides (24× more reference material than everything-cc)
 4. **Educational Progression** — 264-question quiz, beginner → expert path
 **Recommended workflow:**
 1. Learn concepts here (mental models, trade-offs, security)
 2. Use battle-tested configs there (quick project setup)
 3. Return here for deep dives (when something doesn't work or to design custom workflows)
 **Both resources are complementary, not competitive.** Use what fits your current need.

 ## 🎯 Learning Paths
@ -288,12 +397,55 @@ cco   # Offline mode (Ollama, 100% local)
 ## 🔑 Golden Rules
-1. **Start small** — First project: 10-15 lines CLAUDE.md max
+### 1. Verify Trust Before Use
-2. **Read before edit** — Always Read → Understand → Edit (never blind Write)
+
-3. **Test-first** — Write test → Watch fail → Implement → Pass
+Claude Code can generate 1.75x more logic errors than human-written code ([ACM 2025](https://dl.acm.org/doi/10.1145/3716848)). Every output must be verified. Use `/insights` commands and verify patterns through tests.
-4. **Use `/compact`** before context hits 70% — prevention beats recovery
+
-5. **Review everything** — AI code has 1.75× more logic errors ([source](https://dl.acm.org/doi/10.1145/3716848))
+**Strategy:** Solo dev (verify logic + edge cases). Team (systematic peer review). Production (mandatory gating tests).
-6. **Context = Gold** — Clear CLAUDE.md > clever prompts
+
 ---
 ### 2. Never Approve MCPs from Unknown Sources
 18 CVEs identified in Claude Code ecosystem. 341 malicious skills in supply chain. MCP servers can read/write your codebase.
 **Strategy:** Systematic audit (5-min checklist). Community-vetted MCP Safe List. Vetting workflow documented in guide.
 ---
 ### 3. Context Pressure Changes Behavior
 At 70% context, Claude starts losing precision. At 85%, hallucinations increase. At 90%+, responses become erratic.
 **Strategy:** 0-50% (work freely). 50-70% (attention). 70-90% (`/compact`). 90%+ (`/clear` mandatory).
 ---
 ### 4. Start Simple, Scale Smart
 Start with basic CLAUDE.md + a few commands. Test in production for 2 weeks. Add agents/skills only if need is proven.
 **Strategy:** Phase 1 (basic). Phase 2 (commands + hooks if needed). Phase 3 (agents if multi-context). Phase 4 (MCP servers if truly required).
 ---
 ### 5. Methodologies Matter More with AI
 TDD/SDD/BDD are not optional with Claude Code. AI accelerates bad code as much as good code.
 **Strategy:** TDD (critical logic). SDD (architecture upfront). BDD (PM/dev collaboration). GSD (throwaway prototypes).

 # Evaluation: Simone Ruggiero - qmd Token Savings (Medium)
 **Date**: 2026-02-14
 **Evaluator**: Claude Opus 4.6
 **Source Type**: Medium article (tool promotion)
 **Verdict**: ⚠️ **MARGINAL** (Score: 2/5)
 ---
 ## Summary
 Simone Ruggiero (Feb 1, 2026) promotes **qmd** (github.com/tobi/qmd), a local document indexer exposed as an MCP server for Claude Code. Main claim: "95% token savings" by replacing Glob/Grep/Read with indexed semantic searches. The tool indexes codebases locally and serves results via MCP, allowing Claude Code to query an index instead of reading raw files.
 **Key claim**: Replace native Claude Code file operations with indexed lookups to reduce token consumption by ~95%.
 **Source**: [Medium Article](https://medium.com/@simone.ruggiero92) (exact URL from Feb 2026)
 ---
 ## Content Summary
 **Main Points**:
 - **qmd** is a local document indexer by Tobi Lutke (Shopify CEO)
 - Exposes a Model Context Protocol (MCP) server for Claude Code
 - Claims 95% token savings on file exploration operations
 - Token math scenario: 500-line file = ~10K tokens via Read → qmd returns ~500 tokens (summary/chunks)
 - Positions qmd as replacement for Glob + Grep + Read workflow
 - Setup: `qmd index .` then configure as MCP server in Claude Code settings
 ---
 ## Fact-Check Results
 | Claim | Verified | Verdict |
 |-------|----------|---------|
 | **"95% token savings"** | ⚠️ UNVERIFIABLE | No benchmark methodology, no reproducible test. Percentage depends entirely on query type, codebase size, and what "savings" means (input tokens? output? both?) |
 | **"qmd by Tobi Lutke"** | ✅ TRUE | github.com/tobi/qmd exists, authored by Tobi Lutke (Shopify) |
 | **"MCP server for Claude Code"** | ✅ TRUE | qmd does expose an MCP interface |
 | **"500 lines = 10K tokens"** | ⚠️ MISLEADING | Assumes every file read sends full content. Claude Code already has intelligent context management and doesn't blindly read entire files |
 | **"Replaces Glob/Grep/Read"** | ⚠️ OVERSIMPLIFIED | Semantic search complements but doesn't replace exact pattern matching (Grep) or file discovery (Glob) |
 ### Factual Corrections
 **Major issue**: The 95% claim assumes a worst-case baseline (reading entire files raw) and compares against best-case indexed retrieval. Real-world savings depend on:
 1. Whether Claude Code would have read the full file anyway (often it reads specific line ranges)
 2. Whether the semantic index returns the right chunks (precision matters)
 3. Whether the query requires exact matching (where Grep is superior)
 **Context missing**: Article doesn't mention that Claude Code already optimizes token usage via:
 - Line-range reads (offset + limit parameters)
 - Targeted Grep searches (returns only matching lines)
 - reference.yaml pattern (machine-readable index, ~2K tokens)
 ---
 ## Scoring & Decision
 ### Score: **2/5** (Marginal)
 **Scoring Grid**:
 | Criterion | Score | Justification |
 |-----------|-------|---------------|
 | **Source Credibility** | 2/5 | Medium article, author has no established Claude Code expertise. Tool itself is from credible author (Tobi Lutke) but article is promotional |
 | **Factual Accuracy** | 2/5 | Core claim (95%) unverifiable, misleading baseline comparison, missing context about existing optimizations |
 | **Timeliness** | 3/5 | Recent (Feb 2026), MCP ecosystem is active topic |
 | **Practical Value** | 2/5 | Concept valid (semantic indexing) but already covered by existing tools (grepai MCP) |
 | **Novelty** | 2/5 | Semantic code search MCP already exists (grepai), reference.yaml pattern already documented |
 | **Completeness** | 1/5 | No benchmarks, no comparison with alternatives, no discussion of trade-offs or limitations |
 **Weighted Average**: (2+2+3+2+2+1)/6 = **2.0/5**
 ---
 ## Comparative Analysis
 | Aspect | qmd | grepai (MCP) | reference.yaml |
 |--------|-----|-------------|----------------|
 | **Type** | Local indexer + MCP | Semantic search MCP | Static YAML index |
 | **Setup** | `qmd index .` + MCP config | MCP server config | Manual maintenance |
 | **Search type** | Semantic (embeddings) | Semantic (embeddings) | Key-value lookup |
 | **Token cost** | ~500 tokens/query (claimed) | ~500 tokens/query | ~2K tokens (full load) |
 | **Exact matching** | No (semantic only) | No (semantic only) | No (manual keys) |
 | **Freshness** | Re-index required | Auto-indexed | Manual updates |
 | **Already in guide?** | No | No (but used in this project) | Yes (documented pattern) |
 | **Unique value** | None over grepai | Callgraph tracing, callers/callees | Human-curated, zero dependencies |
 **Key finding**: qmd and grepai solve the same problem (semantic code search via MCP). For users already using grepai, qmd adds zero value. For users without either tool, the guide already documents the reference.yaml pattern as a lightweight alternative.
 ---
 ## Why NOT Integrate
 1. **Already covered**: Semantic code search MCP = grepai (same capability, already available)
 2. **Unverifiable claims**: 95% savings claim has no benchmark, no methodology, no reproducible test
 3. **Misleading baseline**: Compares against worst-case (full file reads) while ignoring Claude Code's existing optimizations
 4. **No unique contribution**: Doesn't add new concepts beyond "use an indexer" which is already a known pattern
 5. **Promotional tone**: Article reads as tool promotion, not technical analysis
 ---
 ## Final Decision
 - **Score**: **2/5** (Marginal - Do not integrate)
 - **Action**: **NOT APPROVED** - No integration, no watch-list addition
 - **Confidence**: **High** (concept valid but redundant with existing tools and patterns)
 ### What Would Change This Score?
 - **Independent benchmarks** comparing qmd vs grepai vs native Claude Code operations → could justify a mention
 - **Unique feature** not available in grepai (e.g., cross-repo indexing, natural language queries with context) → could merit evaluation
 - **Adoption signal** from Claude Code community (multiple practitioners reporting real savings) → could revisit
 ---
 **Evaluation completed**: 2026-02-14
 **Result**: Score 2/5 rejected. Concept valid (semantic indexing reduces tokens) but already covered by grepai MCP and reference.yaml pattern. Core claim (95% savings) is unverifiable and uses misleading baseline. No integration into guide.

 | Forks | 2 | 38 | Active development community |
 | Releases | 7 in 13 days | 30 in 23 days | Sustained rapid development |
 ### Score Update: 4.5/5 → **5/5**
 **Justification**: All "Path to 5/5" criteria from v0.7.0 evaluation met or exceeded:
 - Community growth: 17 → 446 stars (target was 50+) - **exceeded 9x**
 - Community validation: 700+ Reddit upvotes (target was public case studies) - **exceeded**
 - Org migration: dedicated rtk-ai GitHub org - **maturity signal**
 - Multi-language: Python + Go added (target was stability) - **exceeded**
 - 30 releases in 23 days with no reported regressions - **stability confirmed**
 The fork distinction (`FlorianBruniaux/rtk`) is no longer relevant - all features merged upstream and the project migrated to the `rtk-ai` org.

 Cette evaluation avait:
 - Decouvert que Anthropic publie deja les prompts officiellement
 - Genere l'integration dans `guide/architecture.md:354-380` ("System Prompt Contents")
 - Ajoute les entrees dans `machine-readable/reference.yaml:217-220`
 - Conclu au watch-only pour cette URL

 ## Evaluation Score: 2/5 (Marginal)
 ### Justification
 La ressource est **deja referencee et documentee** dans le guide:
 | Aspect | Statut dans le guide |
 |--------|---------------------|
 | URL officielle | `architecture.md:358` — lien direct |
 | Reference YAML | `reference.yaml:217-220` — 4 entrees |
 | Opus 4.6 | 62 mentions dans 7 fichiers (pricing, adaptive thinking, API, agent teams) |
 | Evaluation existante | `system-prompts-official-vs-community.md` score 2/5 |
 Le contenu specifique (formatting rules, safety rules, evenhandedness) concerne **Claude.ai/Mobile**, pas Claude Code CLI. La note a `architecture.md:380` le dit deja.

 ## Comparative Analysis
 | Aspect | Cette ressource (Feb 2026 update) | Notre guide |
 |--------|-----------------------------------|-------------|
 | Opus 4.6 model info | System prompt date 5 Feb 2026 | 62 mentions, pricing, adaptive thinking |
 | Knowledge cutoff dates | "End of May 2025" explicite | Pas documente explicitement |
 | Formatting rules (anti-lists, CommonMark) | Detaille | Absent (mais concerne Claude.ai, pas CLI) |
 | Safety/moderation rules | Detaille | Couvert dans `security-hardening.md` (cote pratique) |
 | Reminder system | 6 types listes | Absent (mais plomberie interne Claude.ai) |
 | Beta products (Chrome, Excel, Cowork) | Liste | Cowork documente, Chrome/Excel en ecosystem |
 | Evenhandedness guidelines | Detaille | Absent (mais hors scope CLI) |
 ---
 ## Challenge Results (technical-writer agent)
 Le technical-writer a **confirme le score 2/5** avec ces observations:
 ### Score correct
 La distinction CLI vs Claude.ai est le filtre qui justifie le 2/5. Le guide documente Claude Code, pas Claude.ai.
 ### Trois micro-gaps identifies (non prioritaires)
 1. **Knowledge cutoff dates** pas explicites dans le guide
 2. **Reminder system** non documente
 3. **Frequence de MAJ** de la page non trackee dans le workflow
 ### Score ajuste: 2/5 (pas de changement)
 ### Risques de non-integration
 Quasi nuls. Le seul vrai risque serait de rater une publication future du system prompt **specifique au CLI** sur cette page.

 ## Fact-Check
 | Affirmation | Verifiee | Source |
 |-------------|----------|--------|
 | Opus 4.6 date 5 Feb 2026 | Oui | Page officielle (section header) |
 | Model string `claude-opus-4-6` | Oui | Page officielle |
 | Knowledge cutoff "end of May 2025" | Oui | Page officielle |
 | 6 reminder types listes | Oui | Page officielle |
 | CommonMark formatting requis | Oui | Page officielle (multiple sections) |
 | Beta products: Chrome, Excel, Cowork | Oui | Page officielle |
 | Guide reference deja cette URL | Oui | `architecture.md:358`, `reference.yaml:217` |
 | Evaluation precedente existe | Oui | `system-prompts-official-vs-community.md` (score 2/5) |
 **Corrections apportees**: Aucune. Toutes les affirmations verifiees.
 ---
 ## Recommendations
 ### Actions opportunistes
 Lors du prochain passage sur `architecture.md`:
 1. **Ajouter knowledge cutoff dates** par modele (end of May 2025 pour Opus 4.5/Sonnet 4.5) — info architecture utile, explique pourquoi Claude "ne sait pas" certaines choses recentes
 2. **Ajouter mention du reminder system** (6 types) — explique des comportements "mysteres" (refus sur images, warnings non demandes en longues conversations)
 ### Ce qu'on ne fait PAS
 - Pas de section dediee dans le guide
 - Pas de nouveau contenu sur les formatting rules Claude.ai
 - Pas d'integration des safety/evenhandedness rules (hors scope CLI)
 ---
 ## Decision finale
 - **Score final**: 2/5 (Marginal)
 - **Action**: Ne pas integrer. Watch only. Deja couvert.
 - **Confiance**: Haute (source officielle, fact-check complet, evaluation precedente coherente)
 - **Note**: Deuxieme evaluation de la meme URL. La premiere (Jan 2026) avait conclu a 2/5 et a genere l'integration dans `architecture.md:354-380`. Rien de nouveau ne justifie une mise a jour.

 ### rtk-baseline.sh
 **Event**: `SessionStart`
 Captures RTK cumulative stats at session start for delta tracking. Paired with `session-summary.sh` which computes per-session RTK savings at session end.
 **Configuration**:
 ```json
 {
  "hooks": {
    "SessionStart": [{
      "hooks": [{
        "type": "command",
        "command": "~/.claude/hooks/rtk-baseline.sh",

      }]
    }]
  }
 }
 ```
 ### session-summary.sh (v3)
 **Event**: `SessionEnd`
 Full session analytics with 15 configurable sections, CLI config tool, and JSONL logging.
 **Sections** (all configurable via env vars or config file):
 | Section | Default | Description |
 |---------|---------|-------------|
 | `meta` | always | Session ID, name, branch |
 | `duration` | always | Wall time, active time, turns, exit reason |
 | `tools` | always | Tool calls breakdown (OK/ERR) |
 | `errors` | on | Error details grouped by tool |
 | `files` | on | Files read/edited/created with top edited |
 | `features` | on | MCP servers, agents, skills, teams, plan mode |
 | `git` | on | Git diff summary (+/- lines, files changed) |
 | `loc` | on | Lines of code written via Edit/Write |
 | `models` | always | Model usage (requests, tokens) |
 | `cache` | always | Cache hit rate |
 | `cost` | always | Estimated cost (ccusage or pricing table) |
 | `rtk` | on | RTK token savings (delta from session start) |
 | `ratio` | on | Conversation ratio (interactive/auto turns) |
 | `thinking` | off | Thinking blocks count |
 | `context` | off | Context window estimate (peak %) |
 **Log File**: `~/.claude/logs/session-summaries.jsonl` (structured JSONL with all metrics)
 **Configuration Priority**: `env vars (SESSION_SUMMARY_*)` > `config file (~/.config/session-summary/config.sh)` > `defaults`
 **Environment Variables**:
 | Variable | Default | Description |
 |----------|---------|-------------|
 | `NO_COLOR` | - | Disable ANSI colors |
 | `SESSION_SUMMARY_SKIP` | `0` | Set to `1` to disable summary |
 | `SESSION_SUMMARY_LOG` | `~/.claude/logs` | Override log directory |
 | `SESSION_SUMMARY_FILES` | `1` | Files section toggle |
 | `SESSION_SUMMARY_RTK` | `auto` | `auto` / `1` / `0` |
 | `SESSION_SUMMARY_GIT` | `1` | Git diff toggle |
 | `SESSION_SUMMARY_ERRORS` | `1` | Error details toggle |
 | `SESSION_SUMMARY_LOC` | `1` | Lines of code toggle |
 | `SESSION_SUMMARY_RATIO` | `1` | Conversation ratio toggle |
 | `SESSION_SUMMARY_FEATURES` | `1` | Features used toggle |
 | `SESSION_SUMMARY_THINKING` | `0` | Thinking blocks toggle |
 | `SESSION_SUMMARY_CONTEXT` | `0` | Context estimate toggle |
 | `SESSION_SUMMARY_SECTIONS` | (all) | Comma-separated section order |
 **CLI Config Tool** (`session-summary-config.sh`):
 ```bash
 session-summary-config show              # Current config with section status
 session-summary-config set git=0         # Disable a section
 session-summary-config set thinking=1    # Enable a section
 session-summary-config reset             # Reset to defaults
 session-summary-config sections          # Show section order
 session-summary-config sections "meta,duration,tools,cost"  # Minimal output
 session-summary-config preview           # Demo output with current config
 session-summary-config install           # Install hooks in settings.json
 session-summary-config log 5             # Last 5 session summaries
 ```
 **Requirements**:
 - `jq` (required for JSON parsing)
 - `ccusage` (optional, for accurate cost calculation)
 - `rtk` (optional, for token savings tracking)
 **Example Output** (all sections enabled):

 ### Outcome Engineering — o16g Manifesto (Cory Ondrejka)
 **URL**: [o16g.com](https://o16g.com/)
 **Author credentials**:
 - CTO at Onebrief (military command AI platform)
 - Co-creator of Second Life (Linden Lab CTO)
 - Former VP Google Experience (1,500+ engineers, advisor to Sundar Pichai)
 - Former VP Mobile Engineering at Meta
 - Published: February 13, 2026
 **Content summary**: Philosophical manifesto proposing 16 principles for shifting from "software engineering" to "outcome engineering" — prioritizing measurable results over code output. Organized in two parts:
 1. **Goals** (1-8): Human intent guides agents, verified reality over metrics, budget-based management replacing backlogs, creation over tedium, map context before dispatch, build aggressively to test hypotheses, analyze failures as learning artifacts
 2. **Building** (9-16): Agent orchestration, constitutional encoding, knowledge graphs, priority systems, documentation, continuous improvement, risk gates, outcome auditing
 **Cultural positioning**: The naming "o16g" follows the numeronym pattern (i18n, k8s, a11y) — designed for community adoption. Honeycomb cited it in their 10-year manifesto. Talent500 picked up the term on publication day. Posted on Hacker News. Positions itself as a successor framework to software engineering for the agentic era, comparable in ambition to the Agile Manifesto (2001) for its era.
 **Alignment with this guide**:
 | o16g Concept | This Guide Reference |
 |--------------|---------------------|
 | Engineer → outcome architect | Mental Model: orchestrator pattern (ultimate-guide.md:2360) |
 | Risk gates blocking delivery | Production Safety rules (production-safety.md) |
 | Agent orchestration principles | Agent Teams (workflows/agent-teams.md) |
 | Map context before dispatch | CLAUDE.md + Plan Mode (Sections 3.1, 2.3) |
 | Verified reality over metrics | Trust Calibration (ultimate-guide.md:1039) |
 **Value**: Not a Claude Code-specific resource — no commands, configurations, or actionable patterns. Value is cultural: a credible industry leader articulating the philosophical shift that underpins all patterns in this guide. If "outcome engineering" gains traction as a term (like "vibe coding" did), this manifesto is the primary source.
 **Status**: Emerging (day-1 publication). On watch list for community adoption tracking.

-## 11.3 Skills Distribution Platforms
+## 11.3 When to Build vs Use
 For most developers, Claude Code CLI provides the right balance of power and simplicity. But understanding when to use pre-built agents versus building custom agents helps you choose the right tool for your needs.
 ### Pre-Built Agents
 **Claude Code, Cursor, Windsurf, Goose**: Ready-to-use CLI or GUI tools optimized for coding workflows. Install and start working immediately.
 **Use when**:
 - You need a coding assistant now
 - Standard workflows (implementation, debugging, refactoring)
 - Want managed updates and community support
 - Prefer fixed costs (subscriptions) over usage-based pricing
 ### Agent Builder Frameworks
 **Google ADK, LangChain, Vercel AI SDK**: Code-first toolkits for building custom agents from scratch.
 **Key features**:
 - **Multi-LLM support**: Use Claude, GPT, Gemini, or local models (often via unified APIs)
 - **MCP-compatible**: Consume the same MCP servers as Claude Code (3,000+ available)
 - **Custom workflows**: Design agent behavior for domain-specific tasks
 - **Embedable**: Integrate agents into your applications
 **Use when**:
 - Building a product around AI agents (not just using one)
 - Need multi-LLM fallback strategies (e.g., Claude for code, GPT for other tasks)
 - Require custom execution flows beyond coding assistance
 - Want full control over prompts, memory, and orchestration
 | Framework | Focus | Claude Support | Maturity |
 |-----------|-------|----------------|----------|
 | **[Google ADK](https://google.github.io/adk-docs/)** | Multi-language (TypeScript, Python, Go, Java) | ✅ Native | Production (17.6K⭐, Renault/Box) |
 | **[LangChain](https://python.langchain.com/)** | Python/JS ecosystem, largest community | ✅ Via `@anthropic-ai/sdk` | Mature (100K+⭐) |
 | **[Vercel AI SDK](https://sdk.vercel.ai/)** | Edge/streaming, React-first | ✅ Native provider | Active (15K+⭐) |
 ### Direct API
 **Anthropic API, OpenAI API**: Raw LLM access without agent scaffolding.
 **Use when**:
 - Building simple chatbots or single-purpose bots
 - Maximum flexibility, minimal dependencies
 - You're handling tool calls, memory, and orchestration yourself
 ### Decision Tree
 ```
 Need coding assistant? → Claude Code
 Building agent product? → ADK/LangChain
 Simple chatbot only? → Direct API
 Multi-LLM required? → Framework (ADK/LangChain)
 Custom workflow logic? → Framework
 Standard dev tasks? → Pre-built agent
 ```
 ### MCP: The Common Standard
 All frameworks (Claude Code, ADK, LangChain) support the **Model Context Protocol** (MCP). This means:
 - MCP servers you build work across tools
 - 3,000+ MCP servers available ecosystem-wide
 - Tools, prompts, and resources are portable
 **Example**: A `mcp-server-github` works with Claude Code, ADK-built agents, and LangChain agents identically.

 ### Code Search & Analysis
 #### Grepai MCP
 **Community server** for semantic code search and call graph analysis via local Ollama embeddings. Searches code by intent ("payment flow", "auth logic") instead of exact patterns, and traces function call relationships.
 **Repository**: [yoanbernabeu/grepai](https://github.com/yoanbernabeu/grepai)
 **License**: MIT
 **Status**: Active development
 **Privacy**: Fully local (Ollama + nomic-embed-text), no data leaves your machine
 **Use Case**: Developer needs to understand unfamiliar codebase → grepai finds relevant code by natural language description and maps function dependencies, without reading entire files.
 **Key Features**:
 | Capability | Details |
 |------------|---------|
 | `grepai_search` | Semantic search by natural language query (e.g., "error handling middleware") |
 | `grepai_trace_callers` | Find all functions that call a given symbol |
 | `grepai_trace_callees` | Find all functions called by a given symbol |
 | `grepai_trace_graph` | Full call graph (callers + callees) with configurable depth |
 | `grepai_index_status` | Health check: indexed files, chunks, configuration |
 **Token Efficiency**:
 | Workflow | Tokens | Verdict |
 |----------|--------|---------|
 | Grep + Read files (brute force) | ~15K | Noisy, lots of irrelevant context |
 | grepai search + trace | ~4K | Targeted, relevant results only |
 | grepai alone (no follow-up) | ~2-3K | Fast discovery |
 **Setup**:
 ```bash
 # Install grepai
 curl -sSL https://raw.githubusercontent.com/yoanbernabeu/grepai/main/install.sh | sh
 # Install Ollama + embedding model
 brew install ollama
 ollama pull nomic-embed-text
 # Initialize in your project
 cd /path/to/project
 grepai init  # Choose: ollama, nomic-embed-text, gob
 # Index your codebase
 grepai index
 # Optional: watch for file changes (auto-reindex)
 grepai watch
 ```
 **Claude Code Configuration**:
 ```bash
 claude mcp add grepai -- grepai mcp
 ```
 **`.mcp.json` (project-scoped)**:
 ```json
 {
  "mcpServers": {
    "grepai": {
      "command": "grepai",
      "args": ["mcp"]
    }
  }
 }
 ```
 **Example Usage**:
 ```
 User: "Find the authentication flow in this codebase"
 Claude: [Uses grepai_search query="authentication flow" limit=5]
 Result: 3 relevant files with line numbers and similarity scores
  - src/auth/middleware.ts:12-45 (0.89)
  - src/routes/login.ts:8-32 (0.85)
  - src/utils/jwt.ts:1-28 (0.78)
 User: "What calls the validateToken function?"
 Claude: [Uses grepai_trace_callers symbol="validateToken"]
 Result: Call graph showing 4 callers across 3 files
  - authMiddleware → validateToken
  - refreshHandler → validateToken
  - wsAuthGuard → validateToken
  - testHelper → validateToken
 ```
 **Quality Score**: **7.8/10** ⭐⭐⭐⭐
 | Dimension | Score | Notes |
 |-----------|-------|-------|
 | Maintenance | 8/10 | Active development, responsive maintainer |
 | Documentation | 7/10 | Good README, MCP integration docs |
 | Tests | 7/10 | CI present, growing coverage |
 | Performance | 8/10 | Fast local embeddings (~2s search), no network latency |
 | Adoption | 9/10 | Growing community, production use in Claude Code setups |
 **Limitations & Workarounds**:
 | Limitation | Workaround |
 |------------|-----------|
 | Requires Ollama running locally | `brew services start ollama` (auto-start) |
 | Index can become stale | Use `grepai watch` for auto-reindex |
 | Not ideal for exact pattern matching | Use native Grep tool for regex patterns |
 | Embedding model download (~270MB) | One-time `ollama pull nomic-embed-text` |
 **Alternatives**:
 | Server | Advantage | Disadvantage |
 |--------|-----------|--------------|
 | **Grepai** | Local, private, semantic + call graphs | Requires Ollama setup |
 | Native Grep | Instant, exact patterns | No semantic understanding |
 | GitHub Code Search | Cloud-based, cross-repo | Requires GitHub, no call graphs |
 **Cross-reference**: See [ultimate-guide.md — MCP Servers: Grepai](./ultimate-guide.md) for detailed usage patterns, prompt strategies, and integration with other MCP servers.

 ### Example 3: Session Summary Hook
 **Event**: `Stop`
 Display comprehensive session statistics when Claude Code ends, inspired by Gemini CLI's session summary feature.
 #### The Problem
 After a long Claude Code session, you might wonder:
 - How much time did I spend?
 - How many API requests did Claude make?
 - Which tools did I use most?
 - What did this session cost?
 Without session tracking, this information is buried in JSONL files that are hard to parse manually.
 #### The Solution
 A Stop hook that automatically displays a formatted summary with:
 - Session metadata (ID, auto-generated name, git branch)
 - Duration breakdown (wall time vs active Claude time)
 - Tool usage statistics with success/error counts
 - Model usage per model (requests, input/output tokens, cache stats)
 - Estimated cost (via ccusage or built-in pricing table)
 #### Implementation
 **File**: `examples/hooks/bash/session-summary.sh`
 **Requirements**:
 - `jq` (required for JSON parsing)
 - `ccusage` (optional, for accurate cost calculation via Claude Code Usage tool)
 - bash 3.2+ (macOS compatible)
 **Configuration**:
 ```json
 {
  "hooks": {
    "Stop": [{
      "hooks": [{
        "type": "command",
        "command": "$CLAUDE_PROJECT_DIR/.claude/hooks/session-summary.sh"
      }]
    }]
  }
 }
 ```
 **Environment Variables**:
 | Variable | Default | Description |
 |----------|---------|-------------|
 | `NO_COLOR` | - | Disable ANSI colors |
 | `SESSION_SUMMARY_LOG` | `~/.claude/logs` | Override log directory |
 | `SESSION_SUMMARY_SKIP` | `0` | Set to `1` to disable summary |
 #### Example Output
 ```
 ═══ Session Summary ═══════════════════
 ID:       abc-123-def-456
 Name:     Security hardening v3.26
 Branch:   main
 Duration: Wall 1h 34m | Active 14m 24s
 Tool Calls: 47 (OK 45 / ERR 2)
  Read: 12  Bash: 10  Edit: 8  Write: 6
  Grep: 5   Glob: 4   WebSearch: 2
 Model Usage         Reqs    Input    Output

 Cache: 1.2M read / 45.3K created
 Est. Cost: $0.74
 ═══════════════════════════════════════
 ```
 #### Data Sources
 The hook extracts data from two locations:
 **1. Session JSONL file** (`~/.claude/projects/{encoded-path}/{session-id}.jsonl`):
 - API requests count
 - Token usage per model
 - Tool calls (extracted from assistant messages)
 - Tool errors (from tool_result with is_error: true)
 - Turn durations (system messages with subtype: turn_duration)
 - Wall time (first to last timestamp)
 **2. Sessions index** (`~/.claude/projects/{encoded-path}/sessions-index.json`):
 - Session summary (auto-generated by Claude)
 - Git branch
 - Message count
 #### Log File
 Session summaries are also logged to `~/.claude/logs/session-summaries.jsonl` for historical analysis:
 ```json
 {
  "timestamp": "2026-02-13T10:30:00Z",
  "session_id": "abc-123-def",
  "session_name": "Security hardening v3.26",
  "git_branch": "main",
  "project": "/path/to/project",
  "duration_wall_ms": 5640000,
  "duration_active_ms": 864000,
  "api_requests": 47,
  "tool_calls": {"Read": 12, "Bash": 10, "Edit": 8},
  "tool_errors": 2,
  "models": {
    "claude-sonnet-4-5-20250929": {
      "requests": 42,
      "input": 493985,
      "output": 2505,
      "cache_read": 1200000,
      "cache_create": 45300
    }
  },
  "total_tokens": {
    "input": 506458,
    "output": 2551,
    "cache_read": 1200000,
    "cache_create": 45300
  },
  "cost_usd": 0.74
 }
 ```
 #### Performance
 - **Execution time**: <2s for sessions up to 100MB
 - **Memory**: Streaming JSONL processing via `jq reduce inputs` (memory-bounded)
 - **Impact**: Runs at session end (doesn't block during work)
 #### Cost Calculation
 **Priority 1**: ccusage tool (accurate, if available)
 ```bash
 ccusage session --id <session-id> --json --offline
 ```
 **Fallback**: Built-in pricing table (as of 2026-02)
 | Model | Input (per 1M tokens) | Output (per 1M tokens) |
 |-------|----------------------|------------------------|
 | claude-opus-4-6 | $15.00 | $75.00 |
 | claude-sonnet-4-5 | $3.00 | $15.00 |
 | claude-haiku-4-5 | $0.80 | $4.00 |
 #### Edge Cases Handled
 - **Empty sessions** (0 API requests): Displays minimal summary
 - **Missing JSONL file**: Falls back to sessions-index.json
 - **ccusage unavailable**: Uses pricing table fallback
 - **No turn_duration entries**: Shows wall time only
 - **Very large sessions** (500MB+): Streams with jq (memory safe)
 #### Installation
 ```bash
 # Copy hook
 cp examples/hooks/bash/session-summary.sh .claude/hooks/
 chmod +x .claude/hooks/session-summary.sh
 # Add to settings.json (see Configuration above)
 # Test it
 echo '{"session_id":"test","cwd":"'$(pwd)'"}' | .claude/hooks/session-summary.sh
 ```
 #### Comparison with Gemini CLI
 | Feature | Gemini CLI | Claude Code (with this hook) |
 |---------|------------|------------------------------|
 | Session summary | ✅ Built-in | ✅ Via hook |
 | Duration tracking | ✅ Wall + active | ✅ Wall + active |
 | Tool calls breakdown | ✅ Yes | ✅ Yes (with success/error) |
 | Model usage | ✅ Requests + tokens | ✅ Requests + tokens + cache |
 | Cost estimation | ✅ Yes | ✅ ccusage or pricing table |
 | Structured logging | ❌ No | ✅ JSONL for analysis |
